I've built a few bikes. One was a nice long low badass mofo.11" stretched molded frame, 10" over girder. Geared for speed, ran a Kaw Z full throttle on the interstate, but it was a stalemate. That was a beast, 4 speed, ran over 80mph in 3rd gear. Rough on the back with a hardtail frame. It sure was pretty though, metalic bronze with ghost designs. That was back in the late 70's.
